Application filed June 1, 1914. Serial No. 842,048.

To all whom it may concern:

Be it known that I, LEWIS A, MAYALL, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Machines for Creasing Card or other Board for Box-Making, of whichthe following is a specification.

My invention has relation to a machine to automatically by a sequence ofoperations upon a sheet of card or other board form creasings for beingthen bent into a unitstructure; and in such connection my said inventionrelates to the constructive arrangement of the different mechanisms insuch a machine for the defined purpose.

Hitherto it has been the general practised method in the making ofcreased sectional sheets to become box-like structures to first creaseone side of the sheet or board, then to shift the sheet or board, tocrease the opposite side and then to perform the same action in respectto the ereasings of the ends; but according to my present invention theentire operations of forming creases in the ends and sides of the sheetor board are conducted automatically in the machine by a sequence offollowing operations performed upon the sheet or board without change ofdirection of the travel of the board in respect to its plane' of travelthrough the machine, that is, the sheet or board is fed into the.machine at one end and turned out at the other end creased on two endsand sides, without manual handling during its momentary travel throughthe machine to complete the creased sectional structure ready for beingformed or bent into the desired shape or configuration for use, as aunit section .of a package holder or container.

My invention consists of a machine such as hereinafter more fullydescribed and claimed.

The nature and scope of my present invention will be more fullyunderstood from. the following description taken in connection with theaccompanying drawings forming part hereof, in which Figure 1, is alongitudinal side elevation of an automatic machine of my invention,found practically efficient and embodying the essential main features ofmy said invention. Fig. 2, is a top or plan View of the product of saiddefined mode, showing how the board is creased first in one end and thenin the opposite end, and then by a sequence of following operations intwo sides; this view showing also by the arrows how the sheet or boardpasses automatically through the machine to be acted upon through saidsequence of following operatlons upon the said board, for creasing thesame, without the machine shifting or changing its plane of momentarytravel to complete such creasings thereof, until droppmg from themachine ready Without further manipulation to be bent up along thecreasings as shown, into an oblong boxlike unit section to provideultimately with a similar sectional unit a package holder or container.Fig. 3, is an enlarged detail view in broken sectional elevation of the.stopoperating mechanism locatcd at the rear of the machine, to posit onreceived board during the formation of the side creases therein. Fig. 4,is a longitudinal central section View of the machine, parts thereof-inthis View, being shown in elevation. Fi gs. 5 and 5, are brokensectional plan views of the machine, partly in section, to disclose respectively detail arrangements of several diflerent mechanisms of themach ne. 6, is a front e-levational view of the main operating mechanismof the said machine. Fig. 7 represents in section and in elevation theconstrrctive arrangement of the plunger creasing devices of the machine.Fig. 8, is an enlarged view of one,-of the plunger creasing devices,showing the character of the creasings of the board by such devices,

shown in action on the board and the par-.

ticular character of creasing at corners in particular, for permittingof the subsequent free bending of the body into required shape, withoutbreaking the fibersl'of the said corners in the bending of the saidboard. Fig. 9, is a side elevation of the character or shape ofcreasings finally derived and in manipulating thereafter it will readilyyield to any bending along the line of such creasings, without breakingthe fibers of the board in order to assume ultimately the form or shapeof the unit section of a holder or container required which ifotherwise, would appreciably weaken the Fig.

creased structure at such points in assuming thereof and a and a itsfinal shape or form. Fig. 10. is anenlarged detailed elevation andsection of the mechanism to permit of the release oftbe board so as tobe fed to receive in sequence therein the respective end creases. V Fig.11, is a view in sectional ferrediarrangement of one of the series ofguide-rolls of the machine for guiding the.

board in its travel throughthe machine to be subjected to the series insequence of aforesaid following operations; and Figs. 12, 13 and 14, arerespectively, enlarged sec tional elevations of certain stop-devices 1and 4. The feed table is provided with an These creasers are as shown inFig. 5, for

adjustable guide a board to be fed positioning the sheet or unto themachine.

The paper being thus positioned as above, is fed crosswise of the tablea, against stops a and (1, located in brackets a and a, carried by thecreasers C and C The paper is fed under guides a, Fig. 5, into contactwith revolving feed rolls a, journaled to a crossshaft a, positivelvdriven by a gear-means to be presently fully explained. On rockshafts b,at the front andrear of the machine are secured pressure-rolls b, forpressing the sheet or board against the rolls a,

feed the sheet or board forward stops o and a. when the said sheet orboard is released by the stops (2 and a, to bring the said sheetor boardinto a true alining position to be acted upon by following operations ofcreasers C and C located on both sides of the center line of themachineand consist of male and female members 0 and 0 The male member isprovided with a T-shaped bar 0 the leg of which is recessed to receive acoiled spring 0 bearing against a T-shaped disk 0*, carried in suitableguides c", which latter are bolted to the leg of the T-har 0 as clearlyshown in Fig. 7. The female member 0, consists of a channelfbar 0, inwhich is mounted an anvil a", supported in position by means of coiledsprings a and 0*,forming as so arranged a. cushion for said anvil. Theplunger 0 of so as to against the female member is journaled in theanvil a",

and bears against a coiled spring a, mounted in the base portion of thechannel bar 0, as clearly shown in detail in Fig. 7. It will beunderstood that the plunger 0 is afforded a vertical movementindependent of the spring controlled cushioning movement of the anvilc", for the purpose of enabling the male die to effect a clean creaseelevation of the prefully illustrated in Figs. 8 and 9.

aided by the female die, without destroying the fibers about the cornersof the sheet or tion by the independent action of the anvil springcushioning the sheet or board, whilethe two dies are in pressure contactwith the respective surfaces-of the sheet or board to form the requiredcrease of the character as above explained, examples of which are I I hemale dies of the respective creasers C and C are carried by cross-bars 0and a,

slidable in guides 0 and 0 provided in the standard A. These cross-barsby ball hearing connections tries 0 carried by a'driven cross-shaft 0",journaled in the upper part of the standard A. The shaft 0, is operatedby a gearwheel 0 meshing with an idler gear 0 and it in turn meshes witha gear at, mounted ona driven shaft d extending across the machineandjournaled to the standard A On the shaft (1 are mounted a series ofeccentrics d operating plungers (1 which by means of ball bearingconnections d support the cross-bar cl, from which projects the malemember d, of the side creaser D. The female member d, thereof, ismounted in the standard A but in other respects structurally is the sameas the creasers C and C hereinbefore fully described. After the sheet orboard C", has been released from the stops a and a, it is pressed intraveling over the feed rollers a and 0. by the pressure rollers b untilthe sheet or board reaches the stops (1 and a. The shiftable guide a inthe meantime having been moved cross-wise of the machine by a roller a,carried by the cross-bar 0 so that when the end of the sheet or boardhas reached a position to be acted upon by the creasers C and C, it willat that moment be in a true alining position to the verticallydescending male members 0, of the said creasers to be acted uponthereby, to

p 0", are connected with plungers c, operated by a series of ecceninsurea well defined crease in the sheet or board C .The creasers C and Cdescend alternately to provide by following operations the end creases 0and (2 in the sheet or board C as clearly shown in Fig. 2. The stops aand a", now release the sheet or board C and it is carried forward bythe revolving rolls a and a", until reaching the stops (I and a, whenthe side creaser D, descends upon the sheet or board C to first form acrease in one side a, Fig. 2, and this creaser D, rises to allow thesheet or board C to be fed forward until reaching the stops 0"" and 0",whenv the said creaser D, again descends to form the other side creasea, Fig. 2, in the said sheet or board.

The. stops a. and a, move up and down in the guide-ways a and a",providedin one side of the female members of the end creasers C and 'C,as clearly shown in Figs. and 10. Motion is imparted to these stops aswell as the stops a and a, by

means of rock-shaftsa, journaled in bear= ings (1 and (1, carried bybrackets a, ex-

tending from the guide-ways.a and a.

' by a bar (1, moved in a vertical direction by means of a chain oflinks a, and a bell crank-lever a, one end of whlch carrles a roller aoperated upon by a cam a,

mounted on a shaft a, which is journaled in the standard A. The bellcrank lever a; is journaled to the rock-shaft b, of the front of themachine, Which rock-shaft operates the pressure-rolls 6 as clearly shownin Figs. 4 and 5. The stops a and a, and c and 0 are operated in theguide-ways 0 and are provided with rock-shafts 0 and 0 journaled inbearings 0 and 0, carried by the standard A. The rock-shaft 0 at one endcarries a'lever 0 on which I is mounted a roller 0 operated upon by abar 0 movable vertically by a cam 0 journaled to the standard A Abracket 0 extends from the bar 0 and carries aroller 0, which isoperated upon by the said cam 0 A coiled spring 0 1s attached at one endto the lower end of the said bracket and at the opposite end to the saidstandard A tomaintain the roller 0 in proper contact at all times withthe working surface of the cam 0 to thereby insure true vertical aliningmovement of the said bar 0 to raise and lower the said stops a and a,accordingly.

It may be here remarked that similar brackets and cams are provided atthe opposite end of the bar 0 for like purposes. The stops c and 0 areconnected with the rock-shafts 0 and 0 by means of the links 0 Theopposite end of the said rockshaft c has secured thereto an arm 0carrying a roller 0, resting upon a vertically moved bar 0 as clearlyshown in Fig. 14. Secured to each end of the bar 0 are brackets 0carrying rollers c, operated upon by cams c Springs 0 are at tached tothe lower ends of the brackets 0 and have their opposite ends attachedto the standards A to thereby enable the roller 0, to ride upon theworking face of the cam 0 to thus impart true vertical alining movementto the bar 0, for raising and lowering the stops c and 0 The.pressure-rollers 6 at both end portions of the machine raise .and lowerto press the sheet or board during its forward movement while the seriesof between rollers I), serve to b and b", as clearly illustrated inFigs; 4,

l2 and 14, the guide I)", being supported by a bracket b secured to thestandard A. The brackets 12 and 6, support the boxlike structures 6 forthe pressure-rolls b*, as clearly shown in Figs. 4 and 5. v

A belt e, from any suitable source of power passes around loose and fastpulleys e and e provided with a shifter e On the shaft e, carrying theloose and fast pul- "leys e and e, is provided a gear-wheel e,

which meshes with the gear (1, mounted on the shaft d his shaft extendsacross the machine and i provided at its opposite end with a sprocke e,and a chain 6 passing around a sprocket e. which is mounted on the shaft6 Said shaft e", is journaled in the standard A and has mounted thereonthe cams and 0 operating the stops 0* and c", as aforementioned. Theshaft d also has mounted on it the belt-wheel e which by means of a belte, revolves the wheel 6, mounted on a shaft e, which latter is journaledto the standard A, and extends across the machine. This shaft e alsocarries similar belt-wheels e and e, which by means of belts 6 and e,operate pulleys e and e to revolve the rollers a and a. v

The gear-wheel d, meshing with the idler gear 0 revolves the gear 0 toimpart motion to the shaft 0 extending across the machine and havingmounted on its opposite end the gear e meshing with an idler e, to drivea gear 6, which is mounted on the shaft 11, and the said gear in turngears with pinions e and e. The pinion e gearing with a gear a, and apinion e drives the shaft a, on which is mounted the two front feedrolls a". The pinion e, meshing with a series of idler gears e, andpinions e drives the centrally located feed rolls a". The last pinion e,of the series mounted on the shaft e drives the belt-wheel e, andthrough the belt 6 and belt-wheel e", is imparted motion to a shaft 6which drives one of said rollers a". On the shaft 6 is mounted a pinione, meshing with an idler gear (2, to impart motion to a pinion 6 mountedon the shaft 6 to drive the other rear feed roll a, at the discharge endof the machine. v

The mode of operation of the machine as hereinbefore described will beexplained, as

follows :-The' sheet or board C is fed into the front of the machineagainst the guide a and stops a and a, and under the guides a, thepressure rolls 1), atthe front of the machine are caused to descend bythe-cam a, rocking the shaft b,this presses the sheet or board into firmcontact with the revolving feed-rollers a, at the front of the mawillhave operated on the edge of the sheet or board to bring it into apositionfor the respective creasers C and C, in sequence to formalternately descending creases of the character shown in Fig. 9,therein, first in one end portion and then in the other end porti0n,-asshown in Fig. 2. Having thus formed the respective end creases, thestops o and a, are withdrawn, and the sheet or board is then free tomove forward until positioned by momentary contact with the stops a anda, at which time the creaser 1), will descend to form the side creaseI), when the creaser D, rises and the stops a and a, are withdrawn sothat the sheet or board may be fed forward by the feedrolls a", againstthe stops 0 and 0" and holding the sheet or board C long enough topermit the creaser D, to, again descend to provide in the said sheet orboard the other side crease c and of a character of creasing such asshown in Figs. 8 and 9; when the last crease is provided, the stops 0and 0", will be withdrawn, and the feed-rollers a", at the rear of themachine will carry the thus creased sheet or board onto the table a ,forbeing discharged therefrom into any suitable receptacle therefor.

It will thus be observed from the foregoing description the entiremomentary following operations in sequence of the machine as aboveexplained, are automatic throughout, and that the sheet or board as itis fed into the machine along the table (1, thereof, passes through themachine unaltered or changed as to its plane of travel to receive therespective end and side creases board, consisting of meanslocated in onepart of the machine to automatically crease the board in one end, meansin another part of the machine to crease the opposite end withoutshifting or feeding said board, means to feed the said creased boardforward, means to then crease one side, means to feed said board, sidecreased forward, means to crease the opposite side and thereby tocomplete the, creasings thereof and each successive defined operationefiected without shifting said board out of the plane of its travel fromthe feeding into the machine to the point to permit of its d scharge andmeans'to then discharge said-board, for being instantly formed into aunit-section.

2. A machine of the character described, compris ng standards havingfront and rear tables, the front table having an adjustable guide forthe board to be fed, stops located in the front of the mach ne'to pos ton said board during its forwa d feed and before anv creases are formedin the board, means to feed said board forward, creasers posit elyactuated to alternatelv crease the board first in one end and then inthe other. without shifting or feed ng said board and then after beingfed forward contacting with supplemental stops located in the rear ofthe machine to permit a second creaser to alternately crease first oneside and then after the board is fed forward to crease the other sideand finally means to release said stop so as to permit the thus creasedboard to be released from the machine. In witness whereof, I havehereunto set my signature in the presence of the two subscribingwitnesses.
